Question re Dual Pi Flex 150x24mm (CR8GPC) - what is the purpose of R1 & R2? #3

Description

@dburr

Hello, I am working with a Jetson Orin NX paired with an Antmicro Orin NX carrier board and a pair of IMX412c Vision Components sensors. I'm using your Dual Pi Flex 150x24mm (CR8GPC) flat flex cable to connect both cameras to the single dual-CSI connector at J7.

What is the purpose of the resistors R1 and R2 on the flat flex cable? I looked at the schematic but could not find any information on these. They appear to have something to do with the VSYNC (aka CAMx_PWDN) signals, but I am unsure what. On my cable these resistors are unpopulated. Would they need to be populated in order for the VSYNC/PWDN signals to work, and if so, what values should I use?

With thanks,
